New to Bitcoin - confused about cycle timing vs hodling strategy

Started my Bitcoin journey two days ago and grabbed some at around 76k. Planning to keep adding small amounts regularly and maybe pick up more during any major dips.

Something has me puzzled though. I keep seeing people talk about these four year patterns where BTC might hit the mid 50s by late 2026 or early 2027. Everyone seems pretty confident about this cycle concept.

But then I notice most of these same people are just holding their coins instead of selling now to buy back cheaper later. As someone whos spent years managing IT systems I usually look for logical patterns but this seems contradictory.

If people really believe in these predictable cycles why not take advantage of them? Wouldnt it make sense to sell before the expected drop and rebuy at better prices?

Maybe Im missing something fundamental here about the strategy. Would love some insight from people whove been through a few of these cycles before.

Your thoughts would be appreciated
